Abstract: ABSTRACT         Disclosed is a discharge drain assembly (for use in a sink) including a drain body and a plug assembly adapted to fit in the drain body which features limited rotational movement between an open and a closed position.  The plug includes a stainless steel strainer with an integral hollow knob having opposed sides which are inwardly concave.  The knob securely but releasably retains a slotted head portion of a spindle.  The spindle has a neck portion for receiving a sealing washer and a lower body portion including three leg portions.  The leg portions support the plug in the open position, restrain rotation in a first direction beyond the open position, and cam the plug to the closed position when rotated in a direction opposite said first direction.  The structure substantially eliminates a "finding" problem common in prior art arrangements and provides a good seal in the closed position.

Abstract: ABSTRACT OF THE DISCLOSURE    An aqueous emulsion of minute particles of calcium hydroxide formed by bringing porous and minute particles of practically pure calcium oxide into reaction with an excess amount of water is brought into reaction with an aqueous solution of phosphoric acid in an inert atmosphere, a milky reaction mixture containing the reaction product, hydroxyapatite is obtained.  After filtering, the separated cake is washed with water and dried to be an aggre-gate of hydroxyapatite having the following properties:          Analytical value of an atomic ratio of Ca/P: 1.67 to 1.69, Mean size of dimention of hydroxyapatite of length:  150 to 1200  .ANG. width:  50 to 400 A, and ratio of length/width:  3 to 10.  Void: 0.2 to 0.8 cm3/g Mean pore-radius: 50 to 150 .ANG..  By firing the filtered cake, a ceramic material of hydroxyapatite having the following physical properties is obtained:          Analytical value of Ca/P  : 1.67 to 1.69, Mean crystal size         : 4 to 20 microns, and Density                   : 3.14 to 3.16 g/cm3.          The mean crystal size of the thus obtained material is larger than that of conventional synthetic ceramic material of hydroxyapatite.          The ceramic material of the present invention is prepared from the purer raw materials than those used for preparing the con-ventional materials.  In addition, even after firing of  the aggregate of hydroxyapatite at a temperature of 1350°C for one hour, no formation of whitlockite occurs, and no structural defects or decomposition occurs and the aggregate is excellent in thermal stability.  This invention relates to hydroxyapatite, ceramic material, implant material and a process for preparing thereof.  The ceramic material is hydroxyapatite ceramic having an excellent thermal stability.

Abstract: QUICK RELEASE SEAL RETAINER                           Abstract A quick release seal retainer adapted for con-necting a seal segment to a base has a clamp member positioned within a slot formed between a projection of a mounting block and the base.  A pair of studs slid-ably extending through a pair of bores in the pro-jection have one end connected to the clamp member and the other end connected to a bar.  In one embodiment a cam clamp mechanism is connected to the mounting block for locking the bar and hence the clamp member at a position at which the seal segment is clamped against the base.  In another embodiment an over-center toggle link means locks the bar and hence the clamp member at a position at which the seal segment is clamped against the base.  Both the cam clamp mechanism and the toggle link means can be easily actuated to one position to release an old seal segment and to another position to lock the new seal segment in place even when the base is at an elevated operating temperature.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an edge gated injection molding system.  An electrically heated sprue bushing is seated in a well in the cavity plate with a centrally extending melt runner passage which branches radially outward with separate channels leading to a number of edge gates in the cavity plate.          An air gap is provided to insulate the hot sprue bushing from the surrounding cooled cavity plate and a hollow seal is provided at each gate to convey the melt across the air gap.  Each seal is in alignment with one of the channels and one of the gates, and has its inner end seated in a recess in the sprue bushing and its outer end abutting against the curved wall of the cavity plate.  The outer ends of the seals are dome shaped so that they are slightly resiliently deformable.  A portion of the wall of the cavity plate is slightly inwardly tapered so that at the gates, the effective combined diameter of the sprue bushing and the seals is slightly larger than that of the well.  Thus, when the sprue bushing is inserted into the well, the seals are slightly deformed against the wall of the cavity plate.  When the sprue bushing is heated to operating temperatures, further deformation occurs, which has the advantage of providing a pressure tight seal against the curved wall of the cavity plate to prevent leakage of the melt into the air gap.

Abstract: "Device for individually separating flat objects, especially postal correspondence and the like, and spacing them at constant distances apart"                           ABSTRACT     A separator-spacer device for flat objects, such as postal correspondence, able to operate equally on a stream of objects or on a loose pack of objects.   The flat objects to be handled are fed into the V space formed by the opposing branches of two bands which are urged resiliently against each other in order to define a first pinch point.   One of these bands is of a material having a high coefficient of friction and moves in the feed direction of the objects, whereas the other band moves at a lower speed in the opposite direction and has a substantially lower coefficient of friction.   The pinch point allows only one object to pass at a time, urged by the band of high friction coefficient.          Downstream of the pair of bands there is provided a conveyor with belts which move at a greater speed than that of the first band, and which form a second pinch point which is spaced apart from the first by a distance less than the minimum length of the objects to be handled.
